Monitoring system and setting method for the same

1. A monitoring system comprising: a camera server that has a camera whose image pickup direction is controllable; and a setting client at which a tracking method of the camera server is set through a network, wherein the camera server includes: detection means for detecting a moving object in a picked-up image obtained from the camera, based on preset setting information of the tracking method; tracking control means for controlling the camera to perform tracking based on a result of the detection by the detection means; and transmission means for sending the result of the detection by the detection means and the picked-up image to the setting client, and the setting client includes: reception means for receiving the result of the detection by the detection means and the picked-up image from the camera server; window display means for displaying an image display window, in which the received picked-up image obtained from the camera and an indicator to indicate a change detection maximum area as the result of the detection by the detection means are superimposingly displayed, and a setting window to make a setting of a tracking method by referring to an image displayed in the image display window; and transmission means for, when detected that setting information concerning a setting of the tracking control means has been changed through the setting window, sending the changed setting information to the camera server.

2. A monitoring system according to claim 1 , wherein the window display means displays a tracking method selection window to make a selection of a tracking method to be executed by the tracking control means of the camera server from among tracking by inter-frame differences, tracking by color detection, tracking by template, and tracking by face detection.

3. A monitoring system according to claim 2 , wherein when brightness of the picked-up image received by the reception means is equal to or less than a predetermined level, the window display means displays a message to recommend the tracking by template in the tracking method selection window.

4. A monitoring system according to claim 2 , wherein when one of the tracking by template and the tracking by face detection has been selected through the tracking method selection window and brightness of the picked-up image received by the reception means is equal to or less than a predetermined level, the window display means changes an initial setting of corresponding one of a window for making a setting of the tracking by template and a window for making a setting of a face area.

5. A tracking setting method for a monitoring system where a setting of a tracking method of the camera server is set at a setting client through a network, a camera server that having a camera whose image pickup direction is controllable, the tracking setting method comprising: detecting, at the camera server, a moving object in a picked-up image obtained from the camera based on preset setting information of the tracking method; controlling, at the camera server, the camera to perform tracking based on a result of the detection; sending the result of the detection and the picked-up image from the camera server to the setting client; receiving, at the setting client, the result of the detection and the picked-up image from the camera server; displaying, at the setting client, an image display window, in which the received picked-up image obtained from the camera and an indicator to indicate a change detection maximum area as the result of the detection are superimposingly displayed, and a setting window to make a setting of a tracking method by referring to an image displayed in the image display window; and sending, when detected that setting information concerning the tracking has been changed through the setting window, the changed setting information from the setting client to the camera server.

6. A tracking setting method according to claim 5 , wherein the window display includes displaying a tracking method selection window to make a selection of a tracking method to be executed in the tracking control of the camera server from among tracking by inter-frame differences, tracking by color detection, tracking by template, and tracking by face detection.

7. A tracking setting method according to claim 6 , wherein when brightness of the picked-up image received is equal to or less than a predetermined level, the window display further includes displaying a message to recommend the tracking by template in the tracking method selection window.

8. A tracking setting method according to claim 6 , wherein when one of the tracking by template and the tracking by face detection has been selected through the tracking method selection window and brightness of the picked-up image received is equal to or less than a predetermined level, the window display includes changing an initial setting of corresponding one of a window for making a setting of the tracking by template and a window for making a setting of a face area.

9. A computer program encoded on a computer readable medium that causes a setting client, at which a setting of a tracking method of the camera server is set through a network, a camera server having a camera whose image pickup direction is controllable, to perform a process comprising: receiving, from the camera server, a result of detection of a moving object and a picked-up image; displaying an image display window, in which the picked-up image received from the camera server and an indicator to indicate a change detection maximum area as the result of the detection are superimposingly displayed, and a setting window to make a setting of a tracking method by referring to an image displayed in the image display window; and sending, when detected that setting information concerning tracking performed by the camera has been changed through the setting window, the changed setting information to the camera server.
